Photo Adventures with Curiosity and Learning

June 10, 2007:Leucauge dromedaria at Rachel's

What a surprise. I saw a spider invading the web of our little L. dromedaria and after a bit of email exchange with Diaqin, it seems that this is the male. Look at the palps - how much larger they are - as if a pair of boxing gloves. Here he is hiding after his woman chased him out of her web. Clearly not interested in playing the mating game at this time.

This guy is very persistent. Here he is, making his way back into her web. His palps (the short arms near her mouth, used for holding stuff and delivering sperm during mating) are not so obvious here, but clearly of the boxing glove vintage

And the target of his affection - who was a bit frustrated by his advances into her web

However, she chased him off and immediately went to a firefly that flew into her web

and started wrapping. I have synthesized an mpeg video of the wrapping process. It was over in about a minute.

all sorts of high speed motion

Amazing acrobatics! See how she uses her legs to orient the silk being extruded from her spinneret and wrap the firefly.

Nearly finished - you can see silk being extruded from her spinneret

Here is a tangle of web stuff - debris from something

The following photos are from a different web. This gives a general idea of the scale. The web is perhaps 1/2 meter in diameter - a central horizontal web with a 3D structure around it.

When I approach this web, just the slightest movement will send her into hiding. Her hiding place is not so hidden, though.

The Leucauge was building a web near our kitchen

Then she caught a fly for lunch
